An agriculture based country like Bangladesh has huge potentials for utilizing biogas technologies. According to an estimate "29.7 billion m_ of biogas can be obtained from the livestock of the country which is equivalent to 1.5 million tons of kerosene (which is the principal fuel in the rural areas). Apart from this, it is also possible to get biogas from human excreta, poultry dropping, waste, marine plants etc. If each family of Bangladesh can be associated with a biogas plant, then only human excreta will give about 10 billion cubic m_ biogas". According to IFRD - there is potential of about four million biogas plants in our country.
